\m/ MetaL \m/ -Design and build thread
I have not done a full-out build thread in a very, very long time. However due to the generous contributions from members of this community, faith in my design capability which I am grateful for and humbled by, and an opportunity to work with a VERY exciting, new driver which very few have seen, I think this will deserve a thread.
I also am using a mid-driver I have been drooling over for some time, and my winnings from Iron Driver to round out the package. Why Metal? The woofer is Aluminium, The mid is Titanium, and the Ribbon is a doped Aluminium alloy n'uff said. The goals are to capitalize on the advantages of metal drivers in the best form possible. Speed, Accuracy, and openness. This thread will take some time to come to fruition however it will represent a build from concept to finalization. I welcome constructive input however I have a fairly good road map on how I will achieve the goals.
The Drivers
Seas L22RN4X/P 8" woofer
Visaton DSM50ffl 2" Dome Midrange - Eton Symphany 3-400 Matched pair
After extensive testing the DSM50ffl did not meet its manufacturer's specifications, a new midrange had to be chosen.
These ribbon tweeters are manufactured in Russia and imported by Roman (R_Carpenter). They are called the AviaWave (updated) for now since that was on the Zip file of extensive data he sent on them. I will have plenty of pictures and a full update on build quality once I receive them in the next week or so. Here are some teaser measurements Roman sent me of his own doing. I am not going to comment on price, or what/where they compete among other brands. I will let the data speak then review them as a comparison once they ae in and part of the system.
Ribbon Responces
Horizontal 0-60 deg
Impulse
Distortion
CSD
Burst Energy Storage
Lastly, Here is the simulation of the Box Alignment chosen for the L22. Graph includes port noise, stuffing effects and the diffraction shelf.
Much more to come as it trickles in. Next steps are receiving the DSM 50's and running them through their paces, Do a baffle layout, and look at what I can get locally for MDF. I would like 1"...Need to call some local lumber stores.

DOme mids can be finiky and I find them to be very application specific. I am hoping this works out as planned lol.
